Abstract

In the wake of October 8, 2005 Kashmir earthquake, the emergency response to Allai and its surrounding areas was severely affected due to the hazard caused by the Sohbat Charra slide zone. This study focuses on the stability of slopes at Sohbat Charra slide zone at Allai District Battagram. Soil and rock samples were collected and tested in the laboratory. The input parameters needed for the analysis mainly included the shear strength parameters that is, cohesion, angle of internal friction and unit weight of the formation materials, these values were obtained from tests conducted in laboratory. Software Slope/W part of Geo-Studio, 2007 and standard charts were used for the slope stability analysis. On the basis of soil properties and slope stability analysis of the site, suitable measures are suggested for stabilizing the Sohbat Charra slide zone. It is hoped that such measures will help mitigate future problems caused by earthquakes in the area.
